Proposal is among nine meant to stop the disturbance from traffic getting worse
The government is considering introducing a nighttime traffic noise standard and reviewing the planning guidelines for noise on housing estates in an effort to stop an already widespread problem getting worse.
The two suggestions are among nine put forward by the Environmental Protection Department for public consultation.
Others include installing more road-noise barriers and resurfacing 72 road sections with low-noise materials. A total of HK$1.1 billion has been earmarked to fit barriers at 18 points this year.
The department will also update a comprehensive noise-level study covering 100,000 buildings. The three-dimensional data may be made available on the department's website.
These measures aim to address emerging noise-pollution trends such as greater road use at night, especially by trucks, and the public's rising quality-of-life expectations.
